The correct statement about the atoms of an element in group 3 and period 4 on the periodic table is:
- The atoms have 3 energy levels of electrons and 4 electrons in the outermost energy level.
Here's an explanation to help you understand why this statement is true:
1. Group 3 elements have 3 valence electrons, which means they have 3 electrons in the outermost energy level.
2. Period 4 indicates the fourth energy level, so the atoms have 4 energy levels of electrons.
3. Combining these two pieces of information, the statement "The atoms have 3 energy levels of electrons and 4 electrons in the outermost energy level" accurately describes the configuration of atoms in group 3 and period 4.
